▎ 摘　　要

NOVELTY - Cathode active material is claimed. The cathode active material is in granular form and its particle diameters Dv10, Dv50, and Dv90 satisfy the relationship as given in the specification. USE - The cathode active material is useful in cathode sheet for lithium-ion battery (all claimed). ADVANTAGE - The cathode active material produces cathode sheet with high compaction density by adjusting the particle size distribution. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) cathode sheet comprising cathode active material; and (2) lithium-ion battery comprising cathode active material, and/or cathode sheet.
